Has anyone heard of the "nub theory"

I have recently heard of the "nub theory" to guess the gender of the baby when you have your NT scan at 11-13 weeks.  Has anyone ever heard of this??  Was it accurate for your child (if you know what you're having)?  I'm dying to find out what DC #2 will be as this will probably be our last and DH is really hoping for a girl this time.

Does that mean you look for a nub on the u/s? I don't think I could trust it since both boys and girls can look the same so early on.

i know they can faily accurately tell gender of the baby at 12-13 weeks depending on the angle of the "nub" boys point up and girls point down....you have to have a good tech and baby in good position though....but i've ready they can be over90% sure at that stage

I've never heard of that. I wonder how you can tell where it's pointing. I'd suck horribly at being a u/s tech. Everything looks the same to me.

I actually read that a couple places, but here's one thats not as technobabbly and also has a picture  of the angle!

Yes, I read all about it on the website PP posted. At my NT scan at 13 weeks my tech said she was fairly certain he was a boy. It was confirmed at my 18 week big u/s. I think it's definitely possible, although not always an exact science. Good luck!
